Yukim will release Aura’s pre-main amplifier “VA 40 rebirth” in November, aiming to return to the origin. The price is 275,000 yen (tax included). “VA 40 rebirth” An anniversary model planned to commemorate the brand’s 35th anniversary. With the name of the first model “VA 40”, it faithfully reproduces the circuit design of the time. In addition, it was developed as a pure analog amplifier with no digital input and no display display, leaving all operations to manual operation. The concept is “fresh music reproduction that clearly demonstrates the advantages of the traditional MOSFET single push-pull”. The output element uses the British EXICON “ECX10P20” and “ECX10N20”, which have been used by high-end brands such as GOLDMUND and NAGRA. With the excellent low-level linearity that has been highly evaluated so far, and the newly acquired high-power response, it appeals as “reviving the dynamism of the exciting music that Aura listened to.” As a layout that maximizes the capabilities of power devices that incorporate numerous high-quality parts, a large heat sink with MOSFETs is placed on top, and the main board is supported upside down with rods underneath. . The main board attached to the bottom of the heat sink can maintain performance without being affected by heat, leading to improved durability of the parts. The single push-pull drive adopted by this model, which places a large heat sink on top, is said to be advantageous for in-focus reproducibility, which is difficult with parallel push-pull, but the minimum unit of four power devices is quite will have a high temperature of As a countermeasure, the MOSFET is firmly fixed to a large heat sink that has excellent damping properties and does not squeal, and is designed to efficiently dissipate heat from the ventilation holes in the lid. By operating at the optimum temperature, performance can be maintained without causing deterioration of characteristics due to heat. The toroidal transformer is custom-made with a capacity of 200VA. As for the other parts used, we introduced a number of high-quality parts selected through sound quality evaluations, such as metal film resistors from VISHAY, high-grade capacitors from the NICHIKON MUSE series, and gold-clad contact relays, to bring us to a new stage. ing. The input terminals on the back of this unit are phono x 1, LINE x 3, output is 50W + 50W (8Ω rating), power consumption is 16W (maximum 210W). The external dimensions are 430W x 76H x 350Dmm, and the weight is 7.2kg.share this article
